I live in L.A. and will be at the game. Just got my tickets ordered this week thru a UCLA alumni. 8 of them. LOL.
I would avoid the bike thing as well. Just because the speed limit is posted as 30-35, no one will adhere to the limit. Also as mentioned before you will not want to be riding back in the dark.
I don't know where all the gang/blue/red talk comes from anymore, that sh#t was in the 80's/90's. Gangmembers now days where all sorts of clothing. I wear red stuff, blue stuff and I don't have any problems. I think you'll be ok.
Otherwise have fun!!! GBR!!!!
